UV Map Checker

The UV Map Checker creates a deterministic checkerboard pattern that serves as a baseline for validating UV layouts in 3D assets. It enables quick assessment of tiling, scale, margins, and seam alignment across textures. Users specify width and height in pixels, tile size, and optional margins and colors to tailor the grid to their workflow. The tool outputs a raster PNG by default and can export SVG or a metadata JSON descriptor for integration into asset pipelines. Conceptually, the generated grid mirrors how texture coordinates map to image space, allowing artists to detect stretching, skew, or sampling artifacts before a full unwrap or atlas packing occurs. The core value lies in early validation: consistent tile squares ensure predictable sampling, while margins help reveal edge artifacts. The tool also supports advanced options like alternate patterns or alpha masks for masking test regions, and it can embed tile count metadata to support automated QA checks. In practice, a texture artist can generate a 256×256 grid with 16×16 tiles, import the image into a material, and visually confirm that each tile renders squarely at multiple mip levels. The combination of deterministic geometry, export flexibility, and metadata output differentiates this tool from simple pattern generators, making it suitable for production pipelines, tutorials, and rapid prototyping.
